REUTERS, NEW YORK - Want to know what was going through Britney Spears' head during her darkest days? Tune in to MTV's 90-minute documentary "Britney: For the Record" to find out.

Airing November 30, "For the Record" documents a three-month period of Spears' life earlier this year, including sessions for her upcoming album, "Circus," and preparations for her appearance on last month's MTV's Video Music Awards.

An MTV spokesperson says "no topic was off limits" during the interviews.

"I sit there and I look back and I'm like, 'I'm a smart person. What the hell was I thinking?,'" Spears says at one point. "I've been through a lot in the past two or three years and there's a lot that people don't know."

"Circus" is due December 2 via Jive Records. The first single, "Womanizer," debuted at No. 96 on the Billboard Hot 100 this week. It should rise substantially on the Hot 100 next week, after its first round of digital sales are factored in.
